2.2 Before you proceed

Take note of the following precautions before you install components into
the system.

•

Use a grounded wrist strap or touch a safely grounded object or
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.

•

Hold components by the edges to avoid touching the ICs on them.

•

Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.

The motherboard comes with an onboard standby power LED. This LED
lights up to indicate that the system is ON, in sleep mode or in soft-off
mode, and not powered OFF. Unplug the power cable from the power outlet
and make sure that the standby power LED is OFF before installing any
system component.

2.4 Central Processing Unit (CPU)

2.4 .1 Ove rv ie w

The motherboard comes with a surface mount LGA775 socket designed for
the Intel® Pentium® 4 processor in the 775-land package.

•

Check your motherboard to make sure that the PnP cap is on the
CPU socket and the socket contacts are not bent. Contact your
retailer immediately if the PnP cap is missing, or if you see any
damage to the PnP cap/socket contacts/motherboard components.
ASUS will shoulder the cost of repair only if the damage is shipment/
transit-related.

•

Keep the cap after installing the motherboard. ASUS will process

Return Merchandise Authorization (RMA) requests only if the

motherboard comes with the cap on the LGA775 socket.

• The product warranty does not cover damage to the socket
contacts resulting from incorrect CPU installation/removal, or
misplacement/loss/incorrect removal of the PnP cap.

2.4 .2 Rem ov in g t he s tor ag e dri ve a sse mb ly

1. Lay the system on its side, then locate and remove three storage drive
assembly screws.

2. Lift the storage drive assembly, then set aside.

2.4 .3 Ins ta ll ing C PU

To install a CPU:

1. Locate the CPU socket on the motherboard.

Before installing the CPU, make sure that the socket box is facing
towards you and the load lever is on your left.

2-4 Chapter 2: Basic installation

2. Press the load lever with your
thumb (A), then move it to the
left (B) until it is released from the
retention tab.

To prevent damage to the
socket pins, do not remove
the PnP cap unless you are
installing a CPU.

2.6 Expansion slots

This motherboard provides two PCI expansion slots, which locate on the PCI
raiser card that is connected to its slot on the motherboard.

2.6 .1 PCI s lo ts

The PCI slots support cards such as a LAN card, SCSI card, USB card,

another cards that comply with PCI specications.

Before installing an expansion card, read the documentation that came
with it and make the necessary hardware settings for the card.

The length of the PCI card should be less than 150mm on the system.

2.6 .2 Exp an si on ca rd in st al lat io n

Make sure to unplug the power cord before adding or removing
expansion cards. Failure to do so may cause you physical injury and
damage motherboard components.

1. Lift the PCI riser card assembly to remove.

2-11ASUS P1/P2-P5945GC

2. Remove the metal cover opposite the slot that you intend to use.

3. Insert the card connector to the slot, then press the card rmly until it
ts in place. Secure the card with a screw.

4. Reinstall the PCI riser card assembly. Make sure that the riser card
connector sits properly on the motherboard PCI slot.

1. Clea r R TC R A M (CLR T C )
This jumper allows you to clear the Real Time Clock (RTC) RAM in

CMOS. You can clear the CMOS memory of date, time, and system
setup parameters by erasing the CMOS RTC RAM data. The onboard
button cell battery powers the RAM data in the CMOS, which includes
the system setup information such as system passwords.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Remove the battery.

3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep

the cap on pins 2-3 for about 5-10 seconds, then move the cap
back to pins 1-2.

4. Re-install the battery.

5. Plug the power cord and turn ON the computer.

6. Hold down the <Del> key during the boot process and enter BIOS
setup to re-enter data.

Except when clearing the RTC RAM, never remove the cap on CLRTC
jumper default position. Removing the cap will cause system boot failure.

Set these jumpers to +5V to wake up the computer from S1 sleep

mode (CPU stopped, DRAM refreshed, system running in low power
mode) using the connected USB devices. Set to +5VSB to wake up
from S3 and S4 sleep modes (no power to CPU, DRAM in slow refresh,
power supply in reduced power mode).

• The USB device wake-up feature requires a power supply that can
provide 500mA on the +5VSB lead for each USB port; otherwise,
the system would not power up.

• The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep mode.

This jumper allows you to enable or disable the keyboard wake-up
feature. Set this jumper to pins 2-3 (+5VSB) if you wish to wake up
the computer when you press a key on the keyboard (the default is
the Space Bar). This feature requires an ATX power supply that can
supply at least 1A on the +5VSB lead, and a corresponding setting in
the BIOS.

The fan connector support cooling fans of 350 mA~740 mA (8.88 W
max.) or a total of 1 A~2.22 A (26.64 W max.) at +12V. Connect the
fan cable to the fan connector on the motherboard, making sure that
the black wire of each cable matches the ground pin of the connector.

Do not forget to connect the fan cables to the fan connectors.

Insufcient air ow inside the system may damage the motherboard

components. These are not jumpers! Do not place jumper caps on the
fan connectors!

comply with USB 2.0 specication that supports up to 480 Mbps

connection speed.

Never connect a 1394 cable to the USB connectors. Doing so will
damage the motherboard!

Do not forget to connect the 4-pin ATX +12 V power plug;

otherwise, the system will not boot.

• Use of a PSU with a higher power output is recommended when

conguring a system with more power-consuming devices. The

system may become unstable or may not boot up if the power is
inadequate.

• Make sure that your power supply unit (PSU) can provide at least
the minimum power required by your system.

5.2 BIOS setup program

This motherboard supports a programmable rmware chip that you can

update using the provided utility described in section “2.1 Managing and
updating your BIOS.”

Use the BIOS Setup program when you are installing a motherboard,

reconguring your system, or prompted to “Run Setup”. This section
explains how to congure your system using this utility.

Even if you are not prompted to use the Setup program, you can change

the conguration of your computer in the future. For example, you can

enable the security password feature or change the power management

settings. This requires you to recongure your system using the BIOS Setup
program so that the computer can recognize these changes and record
them in the CMOS RAM of the rmware hub.

The rmware hub on the motherboard stores the Setup utility. When you

start up the computer, the system provides you with the opportunity to
run this program. Press <Del> during the Power-On-Self-Test (POST) to

enter the Setup utility; otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, restart the system by pressing
<Ctrl+Alt+Delete>, or by pressing the reset button on the system chassis.
You can also restart by turning the system off and then back on. Do this

last option only if the rst two failed.

The Setup program is designed to make it as easy to use as possible. Being
a menu-driven program, it lets you scroll through the various sub-menus
and make your selections from the available options using the navigation
keys.

• The default BIOS settings for this motherboard apply for most
conditions to ensure optimum performance. If the system becomes
unstable after changing any BIOS settings, load the default settings
to ensure system compatibility and stability. Select the Load Default
Settings item under the Exit Menu. See section “2.8 Exit Menu.”

• The BIOS setup screens shown in this section are for reference
purposes only, and may not exactly match what you see on your
screen.

• Visit the ASUS website (www.asus.com) to download the latest BIOS
